Product details

Overview

STEVAL-IFS002V2 from STMicroelectronics is a STR9-based MEMS demonstration board designed for rapid evaluation of analog and digital motion sensors. It supports multiple LGA and QFN MEMS packages (LGA8, LGA14, LGA16-A/D, QFN28), integrates configurable I²C/SPI serial memory interfaces (M95xx/M25xx/M34xx), and provides optional voltage regulation (LD2980CMxx) and signal conditioning (TS507ILT op-amps) for sensor output conditioning - used in industrial motion sensing prototyping and embedded inertial measurement validation.

For engineers reviewing the STEVAL-IFS002V2 datasheet, STEVAL-IFS002V2 pinout, STEVAL-IFS002V2 application, or STEVAL-IFS002V2 equivalent, this board serves as a flexible hardware platform to validate MEMS sensor integration with STR9 microcontrollers, assess analog signal chain design (gain/filtering), verify digital interface timing (I²C/SPI), and prototype motion-triggered firmware logic before custom PCB development.

Technical Context

The board centers on an STR9 dongle module, providing ARM9-based host processing with GPIO, analog inputs (8× Ain), external interrupt lines (2× ExtINT), and dual communication buses (I²C + SPI). Its modular MEMS footprint architecture allows physical substitution of up to 10 distinct ST MEMS devices - including LIS302ALB (LGA14 analog), LIS302DL (LGA14 digital), LIS3LV02DL (LGA16 digital), and LIS3LV02DQ (QFN28 digital) - without redesign.

All MEMS interfaces share common power domains and signal routing: analog outputs feed into optional TS507ILT op-amp stages (X/Y/Z/XYZ axes), while digital variants connect directly to STR9's SSP0 and I²C1 peripherals. Memory expansion uses SO8 footprints supporting EEPROM (M95xx), Flash (M25xx), and I²C EEPROM (M34xx), each with dedicated LD2980CMxx regulators and decoupling networks.

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, Switzerland, designing and manufacturing microcontrollers, sensors, power ICs, and analog/mixed-signal components for industrial, automotive, and consumer applications.

This board belongs to ST's STEVAL (ST Evaluation) series - purpose-built reference platforms that accelerate customer evaluation of ST silicon (e.g., STR9 MCUs, LIS3 MEMS) through validated schematics, layout, firmware examples, and comprehensive user manuals.

FAQ

What MEMS sensors are pre-assembled on the STEVAL-IFS002V2?

The board ships with LIS302DL (LGA14 digital MEMS) installed on CN4 and LIS3/2L06/2AL (LGA8 analog MEMS) on U2, per Table 9 and Table 10 of UM0542 Rev 3. All other MEMS positions (U1, U3–U6) are unpopulated and intended for user substitution during evaluation.

Does the board support both I²C and SPI simultaneously for digital MEMS?

Yes - the schematics (Figure 3) show parallel routing of both I²C and SPI signals to digital MEMS footprints. However, only one device can be actively assembled at a time due to shared RDY/INT pins; simultaneous multi-device operation requires careful pin conflict resolution per Section 6.2.

Can the analog MEMS op-amp stages be configured for differential output?

No - the TS507ILT op-amps (U80–U83) are wired in single-ended non-inverting configuration per Figure 4 and Table 12–15. Gain is set by resistor pairs (e.g., R84/R85 for X-axis), and output feeds directly to STR9 analog inputs; no differential feedback path or instrumentation amplifier topology is implemented.

Is the STR9 dongle on this board field-programmable?

Yes - the STR9 dongle includes JTAG/SWD debug headers and is preloaded with bootloader firmware enabling flash programming via UART or USB (as documented in related STR9 application notes). The board provides full access to STR9's debug, reset, and boot configuration pins per Figure 2 block diagram.
